Posted: 26 Apr 2016 01:01 PM PDT For instance, if I look up at a satellite in geostationary orbit, it appears to be standing still. But then, there would be no centrifugal force and it should come crashing down. But from other perspectives, the satellite DOES rotate at the right speed to stay in orbit.

Why does the carboniferous period have a mean surface temp equal or lower than today, when it had 2x the atmospheric CO2? Posted: 26 Apr 2016 08:09 AM PDT The mean rise in surface temperature that's been cause for concern within the last 2-3 decades has been almost always attributed to the rise of atmospheric CO2. The Carboniferous period, a geologic era defined by it's large quantities of flora due to high CO2 density (800ppm to today's 400ppm), had a (theorized) mean surface temperature comparable to current temperatures. What other effects are contributing to the rise of global temperatures if not for CO2? Are other greenhouse gases a greater threat than discussed frequently? Do standard cycles of glaciation play a bigger part in the temperature variance (or lack there of)? submitted by /u/Snaz5 [link] [comments]

How can everything be relative if time ticks slower the faster you go? Posted: 26 Apr 2016 02:22 AM PDT When you travel in a spaceship near the speed of light, It looks like the entire universe is traveling at near-light speed towards you. Also it gets compressed. For an observer on the ground, it looks like the space ship it traveling near c, and it looks like the space ship is compressed. No problems so far However, For the observer on the ground, it looks like your clock are going slower, and for the spaceship it looks like the observer on the ground got a faster clock. then everything isnt relative. Am I wrong about the time and observer thingy, or isn't every reference point valid in the universe? submitted by /u/MrPannkaka [link] [comments]

Is there a word for something that's neither unstable nor stable? Posted: 25 Apr 2016 10:10 PM PDT If you stick a ball on a hill and nudge it, it will roll off the hill. It's unstable. If you stick it in a valley and nudge it, it will roll back. It's stable. If you stick it on a plane with friction, it will just move a little and stay there. It's not really either. Is there a name for that? submitted by /u/DCarrier [link] [comments]

Are there forces on a spacecraft other than acceleration during a flyby? (Powered or unpowered) Posted: 26 Apr 2016 06:32 AM PDT Looking at the Oberth effect (powered flyby) and unassisted flyby, would there be any forces other than F=ma on the craft due to gravity or other issues? If periapsis was low enough, atmospheric friction would probably come into play, but are there other forces? Thanks. submitted by /u/keithgcochran [link] [comments]

Is it possible to use other hadrons to catalyze nuclear reactions akin to photocatalysis of chemical reactions? Posted: 26 Apr 2016 06:22 AM PDT A bit of background: My quantum mechanics course was in the chemistry department and pertained specifically to interactions within electromagnetic force. Sometimes photons are used to put reactants into an excited electronic, vibrational, and even rotational state that has the lowest kinetic (as opposed to thermodynamic) barrier to reaction. This leads to faster reactions at lower temperatures. Is controlled use of other gluons akin to lasers are for photons theoretically possible, feasible, or currently done? What about the bosons that carry the weak force? submitted by /u/Liberals_to_Gulag [link] [comments]

How do photons have momentum? Posted: 26 Apr 2016 04:57 AM PDT Could someone provide the answer without pointing out Einstein's equation saying its incomplete and all? Practically, physically how is it possible for a massless object to have momentum? Analogies are appreciated. submitted by /u/Ashen_Cyborg [link] [comments]

Would moving something at a high speed increase its temperature? Posted: 26 Apr 2016 04:31 AM PDT Temperature is just a measure of average kinetic energy. Say, in a vacuum (where friction from air resistance is... unlikely), would moving an object extremely quickly increase the average kinetic energy of the particles in the object enough to noticeably raise its temperature? submitted by /u/pm_MGSVTPP_steamcode [link] [comments]

Are mass and weight directly related? Posted: 25 Apr 2016 06:04 PM PDT Say you have an object, and you want it to become heavier, without changing its mass (adding external objects). Example: a handheld object for a virtual reality device, in order to achieve a more realistic experience, they controllers need to add weight. Is this somehow possible? Just a random question submitted by /u/Jpalermo99 [link] [comments]

In a Neutron Generator, how is the Neutron Beam "Focused"?

Can isotopes commonly used in food irradiation induce radioactivity through neutron activation? Posted: 26 Apr 2016 02:00 AM PDT I have two trusted sources at ends. This study: http://www.ncbi.nlm.nih.gov/pubmed/18220055 , claims that radioactivity can be induced in food by the isotopes Cobalt-60 and caesium-137, however (understanding wikipedia is not perfect) it explicitly states here: https://en.wikipedia.org/wiki/Induced_radioactivity that; "The isotopes used in food irradiation (cobalt-60, caesium-137) both have energy peaks below this cutoff and thus cannot induce radioactivity in the food". Providing the minimum required energy for this is 2 MeV for deuterium. Is wiki wrong with their MeV requirement, is this study wrong, or can you provide another answer, thanks. Sorry for the formatting, I'm still learning. submitted by /u/Trajjan [link] [comments]

How can propellants push a spacecraft if there's nothing to push off against? Posted: 26 Apr 2016 12:10 AM PDT If a rocket burns fuel to accelerate in space, why does that force push the rocket if there's no atmosphere or mass to push off against? submitted by /u/mustangbanana [link] [comments]

Are elliptical orbits any more stable than circular orbits? Posted: 25 Apr 2016 05:52 PM PDT I'm in an argument with another user on reddit (/u/somerandomguy02), over on /r/todayilearned. Here is the thread. /u/somerandomguy02 believes that all orbits are non-circular orbits because non-circular orbits are more stable than circular ones. I've tried my hardest to convince him otherwise, going as far as providing sources to prove that he is incorrect. I do not understand why he has any reason to believe this other than misunderstanding that the statement "elliptical orbits are stable." means that closed orbits are stable, and not that elliptical orbits are more stable. He also does not understand that circular orbits are a special subset of elliptical orbits, because circles are a special subset of ellipses, and refuses to believe the latter. I know that science is not a democracy, but I think having a large number of people verify that he is incorrect would help lead him to admit that he is incorrect, or at least believe that he is incorrect, so therefore I would greatly appreciate it if you were to confirm this. submitted by /u/Artillect [link] [comments]

If the cooling of one object is caused by the transfer of heat to another object, how does the Earth cool in winter? Isn't space empty?

AskScience AMA Series: I'm Alexis Kaushansky, a Principal Investigator at the Center for Infectious Disease Research in Seattle, WA. I research malaria and the interactions between host and pathogens. I’m excited to talk to you about it. AMA! Posted: 25 Apr 2016 04:53 AM PDT Hello Reddit! My name is Alexis Kaushansky and I serve as a principal investigator at the Center for Infectious Disease Research. My research studies the interactions between humans and pathogens, with a particular focus on malaria. The malaria parasite and other infectious diseases that burden the world cannot survive independently. To cause sickness and travel through the population, they must appropriate resources from the people they infect. Our work aims to identify what pathogens need from their host and use this knowledge to prevent and ultimately eliminate malaria. When malaria parasites are transmitted from mosquito to human, they are first deposited into the skin, then quickly travel to the liver. In the liver, each parasite replicates tens of thousands of times within the confines of a single hepatocyte, a cell in the liver. During this stage of infection, the parasite causes no clinical symptoms, yet elimination of the parasite in the liver prevents disease and transmission and can even elicit sterile immunity from subsequent infection. Our work focuses on the basic question of how the malaria parasite is able to modify its human liver environment in order to counteract host defenses and ensure for its own survival. At CIDResearch, we breed thousands of research grade mosquitoes each week in order to power our bench research projects. Our work critically depends on malaria parasite infection in mosquitoes and production of sporozoites for lab experiments. We maintain state-of-the-art insectaries that breed and house Anopheles mosquitoes. Here are a few of our recent publications: Suppression of host p53 is critical for Plasmodium liver-stage infection. http://www.ncbi.nlm.nih.gov/pubmed/23478020 Malaria parasites target the hepatocyte receptor EphA2 for successful host infection. http://www.ncbi.nlm.nih.gov/pubmed/26612952 To mark April 25 World Malaria Day, I'm taking questions on the research underway to better understand and combat this ancient disease. I will be back at 12 pm ET to answer your questions, looking forward to it! submitted by /u/CIDResearch [link] [comments]

Posted: 24 Apr 2016 09:07 PM PDT I'm aware entropy can be thought of as "unusable energy" but what does that even mean? How does this occur?

Do short trees bud/blossom faster than tall trees? Posted: 24 Apr 2016 06:40 PM PDT I was out for a walk today, and I made an observation that most of the tall trees that I saw were still bare, whereas most of the short trees had blossomed. Is this because it takes longer for tall trees to draw nutrients up the trunk in the spring than short trees? Or is it because the "tall trees" are really just a different species and would take longer to blossom even if they were shorter? submitted by /u/taedrin [link] [comments]

How would a person with slight to moderately low levels of grey matter function? White matter as well?

What is Doppler/Laser Cooling (and other questions related to the practice)? Posted: 25 Apr 2016 05:21 AM PDT Hi there, science people! I have a few questions about Doppler Cooling! Lets get started :) Ive done a little research on the topic and I know that in at certain frequency red-shifting occurs and atoms moving away "ignore" the photons flying at them while atoms moving towards the photons absorb them, gaining their momentum which slows the atoms down. My question is about this "ignoring," what is that in more technical terms. When the atom absorbs the photon it will be in a higher energy state and will return to a lower energy state and release a photon with the same frequency that was emitted. Wouldn't the momentum be transferred back into the photon and the atom remain moving with the same kinetic energy as before? (Does it have something to do with the angle the photon is absorbed/emitted?) What temperatures have been reached using Doppler cooling? What are the practical applications of cooling to such a low temperature? What principles of quantum mechanics are used in understanding doopler cooling? Sources would be great. Thank you so much! submitted by /u/outside_joker [link] [comments]

Liquid nitrogen excessive boiling before critical temperature? Posted: 24 Apr 2016 10:03 AM PDT I've used liquid nitrogen for the last few years as a low temperature reference point for the calibration of PRTs (Platinum Resistance Thermometers). The process of which involves a filling a 2 liter dewar flask and submerging a copper block inside of it. The process of getting the copper down to the boiling point of the liquid nitrogen takes about 10-12 minutes, for those curious, but what I want to know happens RIGHT before it reaches thermal stability. About 30 seconds before thermal stability the nitrogen starts to boil more vigorously. It "erupts" from the holes at the top of my test set up and shoots a huge cloud of water vapor (from the air) and droplets of liquid nitrogen everywhere.

What type of computer / communications hardware / software was used on the Lunar Landing Missions (Apollo)? Posted: 24 Apr 2016 03:39 PM PDT Couldn't find much info on: Computing power of Lunar Orbiter / Lunar Landing Craft Radio & Television broadcasting Equipment & Frequencies / Power Needed to transmit to earth Navigation systems used Considering commercial air travel relies Heavily on "fly-by-wire" / computerized Systems, GPS, VHF radio, RADAR, etc, How did NASA pull off getting a Lander, As well as a Lunar Escape / Earth Re-Entry craft to the moon and back without the items less-intense aviation such as Commercial Air Traffic uses today. It's my understanding that a smart-phone today likely has more computing power than NASA had in its entire Mission Control in 1969. How was this feat accomplished lacking the hardware and software we have today? (Which almost begs the question "why haven't we ever returned to the Moon?" Given it should be exponentially easier in 2016 than it was in the late 1960's / early 1970's) submitted by /u/PoppingZitz [link] [comments]
